CommonJS-typed package (`"type":"commonjs"`) resolved as ESM for a client module

_Found running the official Next.js e2e test suite against vinext (vinext 1.0.0-beta.8, Next.js 16.2). Error line is from the suite's own output._

**Fixture:** `test/e2e/app-dir/client-module-with-package-type`

**Symptom:** a dependency declaring `"type":"commonjs"` resolves as ESM (`lib-cjs: esm`).

**Repro:** a client-imported dep with `"type":"commonjs"`; assert it loads as CommonJS.

Start with the fixture at test/e2e/app-dir/client-module-with-package-type and run the official Next.js e2e test suite to reproduce the reported output. Trace how the client-imported dependency declaring "type":"commonjs" is resolved, and consider the issue done when the fixture asserts that it loads as CommonJS rather than ESM.
